I don't even think about it. I'll just adjust my shirt and go on with life. Are you afraid of brandishing by fixing your shirt? I think you would be just fine uncovering your weapon and going on with shopping. Maybe by your actions of trying to hide what you were fixing drew more attention to you then just doing it. I don't have much along the lines of hips so when walking down the street or in a store I must adjust my waist band which also means a quick holster adjustment. Its just second nature and any LEO will (should) under stand. I see them mess'in with their holster and belt all the time. I also am waiting for my CCW from jeffco. Still have up to 67 days left.
